Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed June 28. 1906. Serial No. 323.333.

. To all whom it ma'y concern:

Beitknown thatwe,RoY'HUNTMoRR1s and ELVIN E. TOWNSEND,-CitiZ6nS of the United States, residing at Oakland, in the county of Alameda and State of California, have inventedcertain new and useful Improvements in Fastening Devices for Pneumatic- Tire Protectors; and We do declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others-skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in adjustable tire rotector fastening devices.

The object o the invention is to provide an attaching device for pneumatic we protectors having means whereby the same may be adjusted for connection with various sizes of wheel rims, and means whereby the protector ma be drawn and held around the tire, said fastening device being constructed to ermit the application of the protector w e the tire is inflated.

With the above and other objects in view, the invention consists of certain novel features of'construction, combination and arran ement of parts, as will be hereinafter descri ed and claimed.

I In-the accompanying drawings :Figure 1 is a side view of a portion of a wheel rim and tire, showing the application of the protector and the fastening devices thereto; Fig. 2 is a vertical, cross sectional view of the same;

Fig. 3 is an enlarged detail view of one of the ad usting bolts and connecting plates; and Fig. 4 is a detail sectional View through'the rim engaging or clamping blocks.

Referrlng more particularly-to the drawings, 1 denotes the rim, and 2 denotes the tire, which is here shown as a pneumatic tire. Ada ted to be applied to the tread and sides oft e tire is a protecting strap or sheet 3, which may be formed of any suitable material.- The sheet or strip 3 is provided at intervals al'on its upper edge with a ertures 4, which are adapted to be engaged y hooks 5 formed on and projecting laterally from the outer side ofconnecting or holding plates 6.

The plates 6 are pivotally mounted mid- Way between their ends in the bifurcated lower end of adjusting bolts 7, the upper ends a of which project through conicalsha ed holes 8 formed in ears 8 on the attacl iin blocks 9 and 10. The upper ends of the b0 ts 7 are provided with adjusting nuts 12, the lower sides of which are preferably convex to fit and readily turn in the upper .flanges 13, which when the blocks are brought together form a rectangular passage or recess into which the inner edge of the wheel rim 1 projects when the blocks are aplied thereto. The block 9 is formed with a aterallyrojectin threadedlug o'r stud bolt 14, w 'ich is at apted to be screwed into a threaded aperture 15 formed in the adjacent block, thereby securely clamping the two blocks together upon the opposite sides of the rim and providing for the adjustment of the blocks to fit any width of rim.

By means of an attaching device or fastener constructed as herein shown and described, the protecting strip or sheet of the tire may be securely held in place and stretched around a tire after the same has been arranged in place and by keeping the nuts 12 tight, the protecting strip will be kept stretched and held in place.

From the foregoing description, takenin connection with the accompanying drawings, the construction and operation of the invention will be readily understood Without requiring a more extended ex lanation.

Various changes in "the orm, proportion and the minor details of constructionmay be resorted to witho t departing from the principle or sacrificing any of the advantages of this invention, as defined by the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters-Patent, is

1. In a fastening device for pneumatic tire protectors, a pair of blocks, each provided with a erforated car and a longitudinally dis ose flange, said perforations being conica and the flanges being oppositeeach other, whereby a recess is formed between the flanges when the blocks are in position, one of said blocks bein provided with a transverse screw-threaded other one with a screw-threaded lug adapted to fit in said aperture and hold said blocks together with said flanges in engagement with the rim of a wheel when in osltion, a nutted bolt through each car an a hooked plate pivotally secured to the lower end of said bolt adapted to receive the perforated edge of the tire protector.

aperture, and the 2. In a fastening device for pneurnatic tire protectors, a pair of blocks, each provided with a perforated ear and a lon itudinallydisposed flan e, said perforation eing conical below an concave on top and the flanges being opposite each other, whereby a recess is formed between the flanges when the blocks .are in position, one of said blocks being provided with a transverse screwthreaded aperture and the other one with a threaded lug adapted to fit in said a erture and hold said blocks together with their flanges in en agement with the rim of a wheel, a bolt t ough the perforation in each ear, the nut of which is convex on its under 15 side and the lower end of the bolt is bifurcated, and a plate pivotally secured in each bifurcation provided with hooks for engaging with the perforated edge of the protector.

In testimony whereof we have hereunto 20 set our hands in presence of two subscribing witnesses.
